Patenteapec. 24, 190W.

Be it knownthat I, RALPH E; BRIs'roW,` a

' citizen of the United States, residing at Denfillinv and .empt ing ofthe tank l f lent flush tank provided with a suitable pis ver,in thecounty of Denverand State of Colorado, have invented certain new andusevful Improvements in Flush-Tanks; and I' do Ahereby declare thefollowin to be a full, clear, and exact description o the invention,such as will enable Others skilled in the art to which it appertains tomake and use the v My invention relates to the construction of'lushtanks for Water-closets, which tanks are ada ted to be located at apoint'below the bow of the closet, as for instance beneath the adjacentto the bowl, whereby flush` tank,

and valve mechanism maybe conand vthe noise attendant .upon 'the may bepipin cealeg,

-m ed, or entire y suppressed.

'c To this end the mam feature of my inven tion embraces a closedcylindrical or equivaton and having water ways leading to and fromtheflush-tank On'opposite sides of the piston thereof, said water waysprovided with suitable valves, said' parts adapted ito be interposedbetween the closet-bowland the water supply, and valve operatingmechanism adapte simultaneously to open or alternately close the valvesof the Water Ways,

whereby either a continuous flow, or an intermittent and measured volumeof Water may be supplied to the closet bowl at the will of the operator.

There are other, minor features of inventionembracing particularcombinations, and

' s ecial features of elemental construction,

al as will be hereinafter more fully pointed out. t

' In the dra-Wings chosen for the purposcof illustrating my invention,the scope whereof is ointed out in the claims, Fi uij-'e 1 is an en Viewofa flush-tank and va ve' mechan- `ism embodying m invention, showin inconnection with a c oset bowl and the floor which su ports the bowl.Fig. .2 is an. enlarged si eview ofthe flush-tank and valve mechanism,the dotted line showing the change of osition of the .valve mechanism in3 y reversing t e valves. Fig. 3 is a longitudinal central section ofthe flush tank, its piston,

i and the water-ways leading into and from the tank on opposite sides ofthe iston.

Fig. 4 is a transverse section ofthe ilus tank l and water ways leadingto and from the flush tank. K

Like symbols refer to like parts wherever they Occur. 1

I will now proceed to describe my invention -more fully so that othersskilled inthe art towhich it appertains may apply .the

AIn the drawings A indicates a closet-bowl to be iushed, a the liushpipe leading thereto, B the loor which su ports the closet-bowl, and. Cthe vflush-tan located beneath the floorV B, and communicatinf7 with`the bowl through the flush pipe a. he flush tank C may be of anysuitableshap'e and may be supported below the 'bowl A in any suitablemanner, as for instance` upon a shelf or bracket b to which it may bebolted, and may be further securedV against vibration bA braces 7)', b2.As a matter of choice the ilus r tank C is preferably composed-'of aclosed lcylinder 1 `adapted to hold any desired number` of gallons ofwater, and provided with heads 2, 2a having water ways 3, 3.a whichcommunicate with the cylinder l at each end thereof through 'ports 4, 4,and also pro-v vided with asuitable piston 5 having disks or gaskets'l,5a adapted to close one or the other of said ports 4,4, according to theposition of said piston within the cylinder.

6 indicates an inlet pipe. through the me' dium of 'which connection maybe made with the city water pipes, or any other water sup ply llndersuitable head or pressure, and 7 indi tes an outlet pipe leading fromthe iush tank 'C 'to the ilush pipe o which sup plies the bowl A. Eachof these inlet and outlet pi es 6 and 7 is connected, through aninter-me iate T coupling 8 or 8a which constitutes a valve casing, andthrough suitable pipes or inlet ways Ga, 6b and outlet ways 7 a 7l? withthe water ways 3, 3l1 in the cylinder .heads ".2, 12a; and the valve'casings'S, 8f are suitable manner,

The stein of the outlet valve 10 is provided with a cross arm 11carrying pins or posts 11, 11b With which the valve operating mechanismen ages, and the valve E) is coupled to the va ve 10 through the crankarin 12 and intermediate li or rod 13 the said valves 9 and vl() beingso set with relation to eachother that when one end of the tank cylinder1 is open to the inlet pipe (i the yother endof said cylinder 1 willbeopen to the outlet pipe 7. i

The particular ineehanisln devised and preferred by me forsimultaneously reversing the valves 9 and 10, comprises, in addition tothe coupled crank arm 1:2, and cross arm 11 havingpins or posts 11, 11",the twin hooks 14, 14 for alternately' engaging the pins on posts 11,11b of the cross arm l1, said twin iooks being suspended by a suitablerod or link 15 from one arm of a pivoted lever, the other arm of whichlever may be controlled by a push plug 1T located inthe Iloor :idjacentto t ie closet bowl A', or in any other lt will be noted that each ofthe twin hooks 14., tf1-* is an incline or cam .surface 14", thefunction ofwvhich is, on the descent of the t,win hooks, toenlrage thead- 'acent pin or post 11 or 1'1" an cause twin ook 14 or 14 to swingoutof a right line so that when the hook has passed the said pin r11 orl11b as the case may be it shall,with certainty swing back under said pinor post and engage iton the next ascent of said twin h ooks. lt willalso be. noted that the distance between the pins or post l 1 and 11" ofcross .arm llis slightly greater than the distance between the point ofone hook 14 andthe crotch of the other hook 14 consequently when thecross arm 11 is reversed b v the rise ol", the engaging hook the pointof thc otherI or opposite hook will pass to the inside of the o positeor free post of the cross arm vhen t 1e hooks and cross arm are in line.

The construction of the devices being substantially such as hereinbeforepointed ont, the' valves J and l() being in the position shown in Fig.il of the drawings and the Valve mechanism (twin hooks 14, 14, crossarin 11 andcrank arm 12) being in thc position shown in Fig. 2 of lhedrawings, the water from the pressure supply will 4enter through inletpipe (i pass through inlet way 6a and way 3 and by port 4 into the righthand end of the tank cylinder l thus forcing the piston F to the lefthand and causing the Water contained in the cylinder in advance of thepiston to be forced out of the cylinder 1 Y through port 4, way 3,outlet way 7b and outlet pipe 7 to the [lush pipe a and bowl A. Thismovement of the piston to the left con tinues until the piston 5 reachesthe left hand end of cylinder 1 and its gasket or packe ing .5a closesport 4, whereupon the flow of The cylinder 1 to the right handof thepiston (Fig. 3) is now A. ii, il

filled with water which is under pressure from the water su ply butwhich can not escape to the bowl y reason of the position of the outletvalve 10. If now it is desired to institute a continuous How of flushingWater through the bowl A, the plug 17 is operated only sulliciently tocause 'the twin hooks 14, 14 to assume a osition 'midway between thoseshown in f-Ll line and in dotted line, Fig. 2, which willl throw openboth valves 9 and l() and give a-direct passage or way for 'the waterunder pressure iroin the inlet i ie 6 through the ways 3, 3", passagesor in et ways 6b, and outlet'ways 7, 7b to and through the outlet pipes7 and a to the bowl 'owever, it is desired to intermittently supply thebowl A with water, the valves!) and 1l), and twin hooks 1l, 14l are Vleft-in the position shown in Figs. 2 and 3l until the ncxt-{lushing ofAbowl A is required, whereupon the lever 16 is operated to raise thetwin hooks 1-1, 14" into the position shown in dotted lines Fig-Z duringthe course ofwhich movement of the twin'liooks one thereof, 1-1, willengage the pin or post' 11" to the left liaiid in said Fig. '2 andreverse the inclination of said crossarin 11 and crank arm 112 whichwill give a partial rotation to the valves 9 and 10 so that the inletpipe G is put in communication with the left hand end. of' cylinder 1,Fig. 2, through inlet ways o, and way 3,'and the outlet pipe 7 is put incommunication with the. right hand end of cylinder 1 through way 3 andoutlet way 7, whereupon the cylinder 1y ills from the left hand end andempties from the right hand end until such time as the pistonA 5 hasreached the right hand end of cylinder 1 and packing 5 has closed port 4when thellow of llushing water ceases, as before noted.

'nenever, after the operation of the valves 5), 10, by depressing thearni of lever 1G, said lever 16 is released, the twin hook 14 will dropby gravity into the position shown inl'ull line Fig. 2 ih which positionit is ready "for again reversing the valves when the lever the twinhooks I4, 14" may be effected by a i `spring il it is not desired todepend on gi'av- 120 ity and the weight of the hooks, all of which isclearly within the knowledge of a skilled mechanic.
